Support for Soft Delete?

Is there any possibility we can add a feature that allows for soft deletes to be ignored?

https://github.com/graphql-python/graphene-sqlalchemy/blob/db3e9f4c3baad3e62c113d4a9ddd2e3983d324f2/graphene_sqlalchemy/utils.py#L22

I am about to fork this repo so I can add a filter to the query `filter(delete_dt=None)` and that seems like overkill to just add that one line. Is there a simpler way to filter my joins, or potentially a patch we could introduce?

Start at graphene_sqlalchemy/utils.py around line 22 and trace how the query used for joins is built. The issue does not name a test file or settle an API, so first clarify the configurable soft-delete behavior and its scope; done means the agreed behavior is covered by tests.
